Title: Torque detector
Inventor: ITO MASAYUKI
IPC: G01L5/24
Filed: 1989-04-12
Abstract: PURPOSE:To enable the clamping torque of a small screw to be measured by inserting a member made of a pressure sensitive conductive material between the circular spline of a wave motion gear device and the housing of drive means. CONSTITUTION:A torque detector 1 is provided with a wave motion gear device 2 and a motor 3 which is connected to the input shaft of the device 2 and drives a wave motion generator. A pressure sensitive member 7 is inserted between the circular spline 5 of the device 2 and the housing 6 of the motor 3. The member 7 is made of an elastic pressure sensitive conductive material such as a pressure sensitive conductive rubber or the like. When a torque is applied to the member 7 so as to be crushed, the electric resistance value of the member 7 in the direction of a pressure due to the torque changes. Therefore, when electrodes are arranged on both ends in the direction of the pressure and a change in the electric resistance value is measured, the value of the pressure due to the torque can be known and therefore the torque can be measured.

Title: Leakage inspection device for sealed goods
Inventor: FURUSE KIYOSHI
IPC: G01M3/36
Filed: 1980-07-09
Abstract: PURPOSE:To detect the quantity of large or small leakage by using the output of a detecting means for the deformation of the material to be inspected and a differential pressure detecting means which detects the differential pressure of pressurized  container and comparative pressurized container. CONSTITUTION:A pressurized container 11 and comparative pressurized container 12 are provided. The material 17 to be inspected is put in the container 11 and at the same time, the prescribed gaseous pressure is applied. Detecting means for deformation detects the deformation that the material 17 subjects by the application of pressure, as electric signal. Differential pressure detection means detects the differencial pressure within both pressurized containers. When a constant time elapses after performing the application of pressure for the pressurized container, detecting output of deformation detecting is checked. Furthermore, after the elapse of a constant time the output of the differencial pressure detecting means is checked. Large leakage is immediately detected by the output of the deformation detecting means and small leakage is checked for a short time by the differential pressure detecting means. As the output of the differential pressure detecting means corresponds to the quantity of leakage, leaked quantity is also detected.

Title: Thyristor trigger circuit
Inventor: KAGEYAMA MOTOHIRO
IPC: H03K17/725
Filed: 1981-06-15
Abstract: PURPOSE:To surely trigger a main thyristor, by providing a means mitigating sudden change of a current flowing to a trigger power supply at a sub-thyristor triggering. CONSTITUTION:A current flows to a triggering power supply 2 via a normal current applying circuit 3 while a sub-thyristor Q1 turns on. The turning on of the thyristor Q1 is detected with a triggering detection circuit 4 and a photo transistor PT turns off by triggering an LED to interrupt the current of the circuit 3 and a trigger current flows to a main thyristor Q2 via the thyristor Q1. In this case, by using almost the same value of resistors R1 and R2, a current flowing via both the resistors is made almost same, and the current flows via the resistor R2 while the thyristor Q1 is triggered, and when the thyristor Q1 turns on, a current flows via the resistor R1. Thus, a current without sudden change flows from the power supply 2. Thus, a normal trigger current can be given to the thyristor Q2.

Abstract: PURPOSE:To enhance detection sensitivity, by a method wherein high voltage is applied between the metal part of a trouble cable and the earth, and a conductive or semiconductive liquid is scattered to the earth between two points where a voltage direction and current intensity are measured. CONSTITUTION:A cable consisting of a conductor 1, an insulator 2, a metal sheath 3 and an anticorrosion layer 4 is placed on the earth 5. This cable has a damaged part (trouble point) 41 and, when a current is supplied to the cable, a current leaks from the trouble point 41. In order to search for the trouble point 41, one terminal of a high voltage DC power source 6 is connected to the metal sheath of the cable at a certain part and the other terminal thereof is earthed. The current leaking from the trouble point 41 flows to the earth direction as a return circuit current 11. In order to measure the current 11, electrodes 8 are embedded in the earth at desired two points and a potential difference measuring voltmeter 9 is connected between both electrodes 8. At this time, brine 10 is scattered to the peripheries of the electrodes 8 to raise conductivities around the electrodes 8. Whereupon, the current 11 is concentrated at a point between the two points high in conductivity and detection sensitivity can be enhanced.
